PHP Fatal error: Uncaught exception 'InvalidArgumentException' in Type.php

Hi lisota,

Can you paste the full log here and replace your content with fake content for privacy? It is hard to debug without more info.

My current suspicion is a conflict with Co-Authors Plus. I have to test more to confirm.

I have the same issue, and also use the Co-Authors Plus plugin, so that seems like the likely culprit.

It seems like a user object is returned somewhere instead of just a string with the name, if I’m interpreting this correctly.

Hi guys,

That was fixed in 2.7. Thanks for reporting!

The co-authors plugin should also be working seamlessly.

That was quick. Many thanks!
